Defining outputs for jobs

Note: GitHub-hosted runners are not currently supported on GitHub Enterprise Server. You can see more information about planned future support on the GitHub public roadmap.

Overview

You can use jobs.<job_id>.outputs to create a map of outputs for a job. Job outputs are available to all downstream jobs that depend on this job. For more information on defining job dependencies, see jobs.<job_id>.needs.

Outputs are Unicode strings, and can be a maximum of 1 MB. The total of all outputs in a workflow run can be a maximum of 50 MB.

Job outputs containing expressions are evaluated on the runner at the end of each job. Outputs containing secrets are redacted on the runner and not sent to GitHub Actions.

To use job outputs in a dependent job, you can use the needs context. For more information, see "Contexts."

Note: $GITHUB_OUTPUT is shared between all steps in a job. If you use the same output name in multiple steps, the last step to write to the output will override the value. If your job uses a matrix and writes to $GITHUB_OUTPUT, the content will be overwritten for each matrix combination. You can use the matrix context to create unique output names for each job configuration. For more information, see "Contexts."

Example: Defining outputs for a job

jobs:
  job1:
    runs-on: ubuntu-latest
    # Map a step output to a job output
    outputs:
      output1: ${{ steps.step1.outputs.test }}
      output2: ${{ steps.step2.outputs.test }}
    steps:
      - id: step1
        run: echo "::set-output name=test::hello"
      - id: step2
        run: echo "::set-output name=test::world"
  job2:
    runs-on: ubuntu-latest
    needs: job1
    steps:
      - env:
          OUTPUT1: ${{needs.job1.outputs.output1}}
          OUTPUT2: ${{needs.job1.outputs.output2}}
        run: echo "$OUTPUT1 $OUTPUT2"
